Study of Two-Body B Decays to Kaons and Pions: Observation of B->pi+pi-, B-> K+-pi0, and B-> K0pi0 Decays
CLEO Collaboration
Abstract
We have studied charmless hadronic decays of B mesons into two-body final states with kaons and pions and observe three new processes with the following branching fractions: BR(B-> pi+ pi-) = (4.3+1.6-1.4 0.5) × 10-6, BR(B-> K0 pi0) = (14.6+5.9+2.4-5.1-3.3) × 10-6, and BR(B-> K+- pi0) = (11.6+3.0+1.4-2.7-1.3) × 10-6. We also update our previous measurements for the decays B->K+- pi-+ and B-> K0 pi+-.
